I have corrected this problem on unflapped gliders
before. On one glider in
particular one aileron had a bit more undercamber than
the other due some
damage. The temporary fix was to add a small trim tab
on the trailing edge
of the aileron. It worked!


It's easy to experiment by adding a wedge shaped strip
to the underside of
the aileron trailing edge, affixing it with double
sided tape. This will act
like a downward bent trim tab.

.... as well as altering the mass balance, risking
flutter and invalidating the C of A and, therefore,
insurance ... in most countries but not in the USA,
of course, where aerodynamics work differently under
the 'experimental' category.
